Water-Glycol Heat Transfer Fluid — Developed by MORESCO (Japan)

:What Is Direct-to-Chip Liquid Cooling?
Direct-to-chip liquid cooling — also known as cold plate cooling — circulates a heat transfer fluid through metal plates mounted directly on high-heat components such as CPUs and GPUs. Heat moves from the chip into the fluid through the cold plate, then travels through a closed loop to heat exchangers, without any fluid touching the electronics themselves. Because it can be integrated into standard rack architecture, direct-to-chip cooling is often the most practical first step for data centers adopting liquid cooling, including retrofits of existing facilities.
Key Features & Benefits
- Ready to Use, No Dilution Needed: Supplied as a ready-to-use fluid. No on-site mixing or water quality management required, reducing operational risk and setup time.
- Safe, Propylene Glycol-Based Formula: Built on a water-propylene glycol (PG) base chosen for its safety profile and stable heat transfer performance in cold plate loops.
- Material Compatibility Aligned with OCP Guidelines: Engineered for compatibility with the metals, rubbers, and plastics commonly used in liquid-cooled rack systems, in line with Open Compute Project (OCP) guidelines for PG-based heat transfer fluids.
- Circular, Waste-Reducing Design: Fluid reaching the end of its life cycle can be recycled into new raw materials, helping data centers reduce waste fluid challenges and environmental impact.
- Fluid Analysis Support: Ongoing coolant health monitoring available through HLJH's in-house laboratory and MORESCO's specialized fluid analysis service.
Applications
- Cold plate cooling loops in AI training and inference servers
- Liquid-cooled rack deployments in new or retrofitted data centers
- High-performance computing (HPC) systems with direct liquid cooling
Joint Testing & Validation Program
The right cooling setup depends on your server specifications, the number of servers to be cooled, and the installation space available at your site. If you are planning or operating liquid-cooled AI infrastructure - contact us to discuss a pilot evaluation.
Frequently Asked Questions (FAQ)
Q1: What is the difference between direct-to-chip cooling and immersion cooling?
Direct-to-chip cooling circulates fluid through cold plates attached to specific components, while immersion cooling submerges entire servers in a dielectric fluid. Cold plate loops integrate with standard rack designs and are often easier to adopt in existing facilities; immersion suits purpose-built high-density deployments.
Q2: Why does "no dilution needed" matter?
Coolants that require on-site dilution depend on local water quality and precise mixing — both common sources of corrosion and performance problems. A ready-to-use fluid removes these variables, simplifying deployment and protecting your cooling loop from day one.
Q3: How do I evaluate whether immersion cooling fluid suits my facility?
The right setup depends on your server specifications, the number of servers to be cooled, and the installation space available at your site. Share these details with us and we will arrange a pilot evaluation tailored to your facility..
